Understanding the NEXT-GEN Firewall

A majority of companies have some
sort of firewall. Many feel a false
sense of protection and don’t even
know the potential risks of
insufficient armor.

As the first required building block for an overall
network security posture, a firewall is designed
to block unauthorized traffic from penetrating
the network. In addition to a vast array of
security policies a company should employ,
maintaining a firewall can stretch far
beyond a full-time job and ties up a lot
of IT resources.

Having a firewall alone is not enough.
A firewall does not prevent viruses or
malware from entering the network, it
cannot detect intruders nor can it monitor
network traffic. Next-Gen Firewalls are
the evolution of the enterprise
firewall coupled with a number of
network devices filtering and security
features to protect customers.

With so many cybersecurity risks it makes sense to invest in a managed firewall solution.

Traditional firewalls include:

   • Packet Filtering

   • Network Address Translation

   • URL Blocking

   • Virtual Private Networks (VPN)

A centralized virtual or physical appliance (usually an enterprise-grade Palo Alto or Fortinet device) now part of a monthly contract moving it from CapEx to OpEx. As needs grow and a larger device is required, scale the solution without having to purchase a new device.


Updates, patch management, change management and other maintenance is handled 24x7x365 by the vendor. This service will occur within an agreed upon SLA to ensure needs are met in an acceptable timeframe.


Continuous visibility into perimeter security for monitoring, logging, and reporting, all done through a cloud-based portal. View data and analytics, assess trends, utilize logs for audits and compliance requirements.

Managed Firewall Add-Ons

With a next-gen firewall, additional features are layered on with QoS, no additional devices needed.


Additions can include:


Intrusion Detection System (IDS)
IDS will identify malicious traffic targeting the network and provides alerts. Activity is logged to provide an audit trail available for review in a portal.


Intrusion Prevention System (IPS)
IPS works in conjunction with IDS to block malicious traffic and quarantine suspicious traffic. Parameters can be set through the cloud-based portal.


Antivirus software/applications protect inbound and outbound traffic against viruses, worms, trojans and other malware. Protection is at the edge of the network and in real time. Threats are logged in the same SIEM portal.


Content Filtering/URL Filtering
Often the last piece of the security puzzle, content filtering protects your internal network. This web filtering blocks access to websites outside of a company’s Internet “Acceptable Use Policy”, ranging from social media sites and YouTube to gambling and drugs.


Deep Packet Inspection (DPI)

DPI grabs pieces of each packet to thoroughly inspect and identify anomalies or violations of normal protocol/communications.


Application Awareness

Log and track application use throughout the network to create a baseline and use these parameters to set policy around which users can access what.


Active Directory/LDAP Integration

This integration allows a higher level of content/URL filtering based on the user’s roles within Active Directory.

Points to Consider


When considering a new or upgraded solution, assess your entire security policy, upcoming needs and how you plan to evolve your security posture in our ever-changing, high threat environment.


Do you have a security policy?


What does it include?
 • Acceptable use policy?
 • Password policy?
 • Data protection policy?
 • Data destruction policy?
 • Security reporting procedure?
 • Are you compliant with any additional regulatory and compliance standards?


Do you employ any security staff currently?
 • How many employees do you have?
 • Are your employees trained on the security measures in place for them?

What are your security challenges?


What cloud-based “as-a-service” resources do you consume?


Do you run audits on your security?
 • Do your auditors rotate or do you always use the same auditors?
 • When was your last audit?
 • When was the last time you completed a security assessment?
 • Whereareyour biggest security risks within your network?


Do you have an incident response plan?


Do you have a disaster recovery or business continuity plan?
